Product OverviewThe LVCM-019-022-02VAC is a vacuum-compatible linear voice coil motor designed for fast, precise, short-stroke motion in low-pressure equipment. Its compact housing measures 0.750 in (19.1 mm) in outside diameter and 0.875 in (22.2 mm) in length, while providing 0.50 in (12.7 mm) of linear travel.Performance and Vacuum-Compatible ConstructionThe motor delivers 8.1 Oz (2.3 N) of continuous force and 25.7 Oz (7.1 N) of intermittent force at a 10% duty cycle. Its brushless, non-commutated direct-drive construction provides smooth bidirectional force, zero cogging, rapid acceleration and deceleration, quiet operation, and long service life. Motor force is proportional to coil current, and reversing the current reverses the direction of force and motion.Key Features• Vacuum-compatible linear voice coil motor• 0.50 in (12.7 mm) linear stroke • 8.1 Oz (2.3 N) continuous force • 25.7 Oz (7.1 N) intermittent force at 10% duty cycle • Compact 0.750 in (19.1 mm) housing diameter • Brushless, non-commutated operation with no cogging • Direct-drive force proportional to current • High acceleration, rapid reversal, and smooth force control ApplicationsTypical applications include semiconductor and wafer-processing equipment, vacuum optical positioning, laser and electron-beam systems, thin-film and deposition equipment, inspection systems, aerospace test equipment, scientific instruments, and research apparatus requiring compact direct-drive linear motion.Vacuum-System IntegrationConfirm the required operating pressure, allowable outgassing, temperature range, bakeout procedure, cabling, and material compatibility against the product datasheet and the requirements of the vacuum system. Threaded mounting provisions support integration into new or existing equipment; refer to the mechanical drawing for exact thread sizes and dimensions.Mechanical Guidance and Closed-Loop ControlThe LVCM-019-022-02VAC generates linear force but does not provide its own mechanical guidance. The moving and stationary components must be supported by an external bearing, flexure, slide, or other guidance mechanism. For closed-loop position or velocity control, combine the motor with a vacuum-compatible position sensor, servo controller, and current amplifier. Final accuracy and repeatability depend on the sensor, guidance system, load, structural stiffness, controller, and servo tuning. |

The LVCM-019-022-02VAC Linear Voice Coil Motor also
called a Linear DC Motor, has a 1/2 inch (12.7 mm)
stroke and a high force-to-size ratio! It produces
8.1 oz. (2.3 N) of continuous force and 25.7 oz.
(7.1 N) of peak force in a compact 0.750 in. (19.1
mm) diameter x 0.875 in. (22.2 mm) housing. This miniature high speed / high acceleration servo motor may be used in closed loop servo loop. This voice coil motor offers zero cogging, clean, quiet, efficient, low inertia, high acceleration, miniature. This miniature LVCM-019-016-02VAC linear voice coil motor can be easily added to new or existing applications using the precision drilled and tapped 8-32 UNC-2B mounting holes in the coil and housing ends of the motor. |
